1. Different components
ALC blocks are made of ground quartz sand, cement, lime and gypsum as the main raw materials of production, aluminum powder as the foaming agent, through batching, mixing, film injection, pre curing, cutting, and maintenance (10h~12h) under high temperature (180 ℃~200 ℃) and high pressure (10~12 standard atmospheres) Aerator block 。
Shenyang sand Aerated concrete block It is a lightweight porous silicate product made of siliceous materials (sand) and calcareous materials (lime, cement) as the main raw materials, mixed with air entraining agent (aluminum powder), through the process of batching, mixing, pouring, pre curing, cutting, autoclaving, maintenance and other processes.
2. Different characteristics
ALC block has outstanding energy saving and environmental protection effects. It is a new lightweight green wall material with superior performance. It can not only replace sintered clay bricks and small concrete hollow blocks for building walls, but also be used as insulation materials for energy-saving buildings. It is a simple and effective material for building energy conservation.
The sand aerated concrete block uses quartz sand instead of fly ash as silica material, which not only improves the strength of the block, but also improves the impermeability, dry shrinkage γ There has been a qualitative leap in radiation intensity and other aspects.
3. Different functions
ALC blocks are lightweight and high-strength, which can effectively reduce the dead weight of buildings, reduce the foundation and structural investment, and are very suitable for frame structures in various industrial and civil buildings.
Due to the accurate size of sand aerated concrete block products, mortar masonry is not necessary, but adhesive masonry is used instead. The mortar joint is only 2-3mm, and the wall surface can be painted with putty without painting, fundamentally solving the persistent problem of aerated block painting cracks.
